No Stupid Questions
No such thing. Ask away!
!nostupidquestions is a community dedicated to being helpful and answering each others' questions on various topics.
The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:
Rules (interactive)
Rule 1- All posts must be legitimate questions. All post titles must include a question.
All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.
Rule 2- Your question subject cannot be illegal or NSFW material.
Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.
Rule 3- Do not seek mental, medical and professional help here.
Do not seek mental, medical and professional help here. Breaking this rule will not get you or your post removed, but it will put you at risk, and possibly in danger.
Rule 4- No self promotion or upvote-farming of any kind.
That's it.
Rule 5- No baiting or sealioning or promoting an agenda.
Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.
Rule 6- Regarding META posts and joke questions.
Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.
On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.
If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.
Rule 7- You can't intentionally annoy, mock, or harass other members.
If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.
Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.
Rule 8- All comments should try to stay relevant to their parent content.
Rule 9- Reposts from other platforms are not allowed.
Let everyone have their own content.
Rule 10- Majority of bots aren't allowed to participate here.

I read that nasa can't even make saturn v rockets anymore. that the design documents and manufacturing techniques weren't properly archived and everyone that worked on them has died by now. idk if any of that is true.
That’s kind of like saying that ford can’t make a model t anymore.
I’m sure they could, there’s just no reason to.
I’m also sure the contractors that built the Saturn V, those that are still in business, could build equivalent parts today if the government asked.
The Saturn five was an absurdly large rocket designed specifically to get 3 people from earth to the moon. It was insanely expensive per launch, and the only reason it ever flew was because the government was writing nasa blank checks in order to beat the soviets.
Today the government wants a reasonable dollar figure for a launch, and the days of spending a billion dollars per launch are long past.
Yep, $2B/launch now
It is true that we cannot make Saturn V rockets anymore.
The drawings are preserved, and even if they weren't, we have a few examples of unflown ones on display to study. There has been some institutional knowledge lost, several components were made by welding techniques we don't use anymore. Also, many of the components and materials used in the Saturn V are not manufactured anymore and are not available.
Building another Saturn V isn't entirely impossible, but the amount of retooling and re-engineering we'd have to do to the designs to get a flyable rocket we might as well just start over and call it a clean sheet design. Like Falcon Heavy, which put a sports car into solar orbit, or SLS which flew an Orion capsule around the moon in 2022.
